I have a studio monitor setup that is configured like this.
RME UFX II AES output --> MiniDSP DDRC-88D (AES) --> Okto DAC8 Pro (Pure AES Mode) --> Power Amps --> Speakers
The RME is set to 44.1K. It appears that the DDRC-88D is resampling the signal and outputting at 48Khz. Is there any way to change that behavior?
As far as I can tell, the MiniDSP just determines it's sampling rate automatically by looking at it's input, which is from the RME and is 44.1K. I can't find any setting in the miniDSP for it's output rate. Here's what the manual says about the output rate.
"If there is a signal on input channels 1 and 2, all output channels have asynchronous sample rate conversion applied to match that sample rate. Otherwise, all output channels operate at 48 kHz."
The Okto DAC8 also seems to auto set it's rate based on the input stream, the only mention I can find in the manual is that it's free of resampling. So based on that, it should also be set to 44.1k.
However, the main display on the DAC8 shows the sampling rate to be at 48K. Here's a picture of the front panel of the DAC8 showing the 48Khz on the display.
Even though everything seems to be working correctly. I get sound and it all seems to operate as designed. However, I'm wondering if something is resampling the signal, which is not desirable. The only device in the signal chain that has a manual setting is the RME UFX II, which is definitely set to 44.1k.
There seem to be 3 choices of what's going on here.
1. The miniDSP is resampling the signal and changing it to 48K. Based on what I see, this seems to be the case. Even though it should recognize the signal from the RME, which is on channels 1/2 and set everything to 44.1. If that's the case, how can I prevent that?
2. The DAC8 is resampling the signal and changing it to 48K, I don't think that's the case but it could be.
3. The DAC8 has a bug and is just showing 48K on the front panel when it's actually 44.1k. I doubt this is the case, but it's just the only other option.
Any suggestions as to how to make these boxes play nicely would be greatly appreciated. I wish these devices had settings for these things, I find that most "auto set" things don't always work as advertised. Everything sounds really good in this chain, so it's not the end of the world, but I suspect there are some slight improvements to be had if we could remove any resampling that's going on.
